` The invention pertains to space'heaters of the cabinet type andcomprising an inner heating unit and an outer casing enclosing theyheating unit. Heaters of this type are commonly referred 5 to ascirculating heaters in that air is drawn into the open lower end of thecasing for passage upwardly aroundthe heating unit and for discharge atthe top, usually through an open grillevwork. Thus, the heater sets up acirculation of l0' air in the room or space to be heated, and has theeffect of distributing heated air to points remote from the heater.

Theresult of such operation is that when the room or other space to rbeheated is cold, a sub- 15 stantial amount of time is required forthe'heater to raise the room temperature to the desired degree.Furthermore, the space immediately ad-u jacent the sides and bottom ofthe heater is the coolest space in the roo'm.

The primary object of the` present invention isv to provide a heater ofthe general character indicated, whichyis constructed so as to permitofy the conversion of the heater from the circulating type to a directradiating heater, in order that f the temperature of the spaceimmediately'adjacent the heater may when desired be raised withsubstantially greater rapidity than the more remote portions of theroom.

A further object is to provide a.cabinet heater comprising an innerheating unit and an outer casing having front, side and rear wallsspaced laterally from the heating unit and nor-- mally serving to directcurrents of air upwardly through the casing, with certain `of the wallsi constructed to provide one or more movable panels for exposing theheating unit and adapted provide movable panels, which are shown inopenposition.

In the illustrated embodiment of my invention, the heater comprises aheating unit 1, of any ordinary or preferred character, enclosed withina cabinet structure having a base portion 8` supported in elevatedposition by means of legs 9. 5`

Rising lfrom the base 8 is a casing substantially rectangular in formand having a front wall III, side walls Il, and a rearwall I2. Thebottomof the casing is open as indicated at I3, and the ltop It thereof isconstructed to provide an open lo Areferred to, the space immediatelyadjacentthe sides of the heater has a tendency to remain cool until suchtime as the room is thoroughly heated. For the purpose of converting theapparatus 2li into a heater capable of direct radiation laterallythereof, I construct certain of the vertical walls so as to permit ofdirect exposure of the heating unit 1. To this end, I provide,preferably in the opposed side walls II', two movable panels I5 30 eachnormally seated in a frame I6 defining a large opening I1. vInv thepresent embodiment the openings II extend substantially fromy top tobottom of the sidewalls, and are of a width only slightly less than thewidth of the side walls.A 85

When, therefore, the panels I5 are in open position, they no longerserve to directv the airupwardly through the heater, but on thecontrary, permit the direct radiation of heat laterally through theopening to thespace immediately 40.

I have found it desirable to make the panels I5 invthe form of doorshinged at the rear edges of" the frame I6, so that the panels may bepositioned in various angularirelations to the plane of the 45 sideWall. For this purpose, each of the panels is swingably mounted at itsrear edge, in its frame I6, as by meansof hinge rods I8 providing.trunnions I9 at opposite ends engaging in suitable bearings provided bythe frame I6. By this con- 50 struction, the panels may be swung intovarious angular relations to their respective side .walls so `as togovern the amount of direct radiation as may be desired. Moreover, thepanels may be variously positioned so as to serve as reectors fon-5 2'Adirecting the heat outwardly and forwardly In order that the panels maybe set deilni'ly in various desired positions, they are preferablyprovided with means for yieldably holding them in any one oi aplurality' of positions selectively. As herein shown, I provide for thispurpose, on each 'of the panels, an arcuate arm 20 rigid with andprojectinginwardly from the inner face ot the panel through a horizontalslot 2| in the lower portion of the corresponding frame I6. A stop lug22 on the inner end of the'arm is adapted to engage with the frame I6 atone `end of the slot 2| so as to limit the extent of opening movement ofthe panel. With this arm 20 is associated a spring detent 23 engageablewith a series of rccesses 24"' formed in the lower iaceof the arm andspaced a short distancg apart lengthwise of the arm. 'I'he spring detentas shown, comprises a plunger mounted in a tubular casingwhich in turn,is supported in a bracket 26 secured to the underside of the lowermember of the frame I8.

As shown, the panels may be equipped with A handles 21 having latchmembers 28 for engagement with the frame I6 to hold the panels seatedwithin their respective frames I6.

changed at will from the circulating type to a direct radiating heater,and that by the use of movable panels in the side walls of the heater. adefinite and positive control of radiation is rendered possible. As aresult, the utility of the 5 air therethrough, and front, rear and sidewalls l5 spaced from the sides of the unit so as to permit the upwardpassage of air about the unit for discharge through said top wall, eachoi.' said side walls having an opening of a size substantially c'o'-extensive with the adjacent sideradiating surface 20 oi said heatradiating unit, panels having inner heat reflecting walls for closingthe respective openings, and hinge means supporting said panels at theirrear edges for swinging movement on ventical axes whereby to direct'heatradiated side- '25 wise from the heating unit forwardly into the room.
